Error Code [32:406] Total number of data transfer operations on current deduplication database exceeds the maximum allowed value

Article ID:
DD0046
The Data Protection job exceeds the maximum number of streams allowed for the deduplication database.

Symptom

When there are many data protection jobs running concurrently and the associated number of streams to the deduplication database (DDB) exceeds the default value of the Maximum number of parallel data transfer operations for deduplication database parameter, then the following error message is displayed in the Job Controller window, and the Statusof the job is displayed as Waiting:

If the output of the DDBParam qscript with get parameter is zero, then the number of streams for the DDB is configured across the CommCell level by using the Maximum number of parallel data transfer operations for deduplication database parameter.

To reset the value configured by using qscript and the Maximum number of parallel data transfer operations for deduplication database parameter value, run the DDBParam qscript with the set parameter and the paramvalue as 0.

Using the Media Management Configuration parameter

Use the Maximum number of parallel data transfer operations for deduplication database parameter to modify the number of streams for all the DDBs in the CommCell.

On the ribbon in the CommCell Console, click the Storage tab, and then click Media Management.

In the Maximum number of parallel data transfer operations for deduplication database box, enter the number of streams for the data transfer operation.

Click OK.

The data protection jobs resumes after you modify the number of streams and when resources are available.

NOTE: If the value is increased to the maximum range (400), then a risk exists for performance degradation. Increase the value gradually by small increments until you find the optimal value for your environment.
